The HFA II offers a variety of screening and threshold test patterns that meet most clinical
needs. Tables 3.1, 3.2, and 3.3 describe each pattern in order to assist the professional in
choosing the one best suited to the patient’s needs. Appendix E contains diagrams of the
available test patterns.
Screening tests serve an important clinical function by quickly surveying the visual field and
flagging areas that are highly suspect. They answer the question, “Is there a problem?”.
Abnormal test results warrant further investigation with threshold testing. See Table 3.1 for
details about the available Screening tests.
Threshold tests more precisely define the problem by calculating the actual sensitivity level at
each test point. They uncover early depressions and subtle changes in retinal sensitivity. See
Table 3.2 for details about the various Threshold tests.
